Main Menu: Pretty piano right from the start. The woodwind joining in gave me instant JRPG vibes particularly with that sample. Very pretty.
Carnival by the Pier: Nice percussion, nice progression. Steel drum always helps for a summer theme.
Nostalgia by the Park: Nice and cute track. Love the instrumentation.
Wonder by the Aquarium: This is very nice. Like those extra lines around 1:06 and 1:12 etc.
Last Summer Night: Very pretty. I wasn't expecting the drums and I love them! Love this as a final track. Probably my favorite one here.
Nice work!
